Sharjeel Khan and Khalid Latif, who took part in the Pakistan Super League, were provisionally suspended and charged last month over meeting a man suspected of being linked to an international betting syndicate.

Mohammad Irfan became the next victim of the fallout of alleged spot-fixing, with the Pakistan cricket authorities coming down heavily on the reported incidence of fixing had previously also found several current and former Pakistan players in the thick of things.

The PCB has already formed a three-member tribunal headed by a former judge to conduct a probe after the board charged Sharjeel and Khalid with spot-fixing.

He made it clear that if any player is found guilty of spot-fixing, he could end up behind bars.
